The DIN 1629 ST52 seamless steel pipe from Exipei Steel Limited is a non-alloy structural tube designed for mechanical and pressure applications, with a minimum yield strength of 355 N/mm² and tensile strength up to 650 N/mm². The material composition conforms to carbon manganese steel specifications, with carbon content capped at 0.22% and manganese below 1.6%, ensuring good weldability and impact resistance. These pipes are manufactured without seams, enhancing reliability under cyclic stress and high-pressure environments.
The pipe is produced using seamless hot rolling or cold drawing methods, with outer diameters and wall thicknesses tailored to industrial standards. Surface finish is typically mill scale unless pickled, and internal cleanliness is maintained for fluid systems. The ST52 grade is commonly used in machinery frames, hydraulic systems, and structural supports where strength-to-weight ratio is critical. Unlike coated or plated alternatives, these pipes rely on base material properties for corrosion resistance, making them suitable for dry or controlled environments.
Buyers in the mechanical engineering, pipeline construction, and heavy equipment sectors commonly source this pipe for fabrication of pressure vessels and load-bearing components. Orders are typically placed in metric tons, with packaging in steel-bound bundles and end caps. Trade terms include FOB Wuhan or CIF destination, with lead times averaging 30 to 45 days. Mill test certificates and third-party inspection reports are required for international compliance and customs clearance.

Verify the material grade ST52 with a certified mill test certificate showing chemical composition and mechanical properties. Confirm that the heat number on the certificate matches the batch label on the pipes. Request a flattening test result and elongation data, as these are critical for structural integrity. Do not accept generic certificates without batch-specific test data.
Lead time is typically 30 to 45 days after deposit, depending on mill scheduling. Trade terms are commonly FOB Wuhan Port, with CIF options available. Payment is usually 30% advance by T/T and 70% against copy of bill of lading. Incoterms must be clearly stated in writing. Confirm inland transport from Wuhan to the port and container loading schedules to avoid delays.
Perform visual inspection for surface cracks, dents, or scale flaking. Use a caliper to check wall thickness at multiple points and confirm diameter tolerance. Request a report of ultrasonic testing for internal defects. For critical applications, arrange third-party inspection by SGS or Bureau Veritas before shipment. Ensure all documents are in English and match the purchase order exactly to prevent customs holdups.
